Abstract

Moulding materials based on ultra-high molecular weight polyethylene (UHMWPE), containing (A) 85.4-99.87 wt.% base polyethylene (PE) component comprising (a) 10-90 wt.% UHMWPE with a viscosity number (VN) of 1800-4000 ml/g, and (b) 10-90 wt.% HDPE with a VN of 300-1500 ml/g, (B) 0.05-0.5 wt.% thermo- oxidative stabiliser(s), (C) 0.02-1 wt.% fatty acid salt(s), (D) 0.05-2 wt.% amide wax(es), (E) 0-2.0 wt.% paraffin, (F) 0.001-10 wt.% blend component comprising (c) 0.5-100 wt.% fluoroelastomer(s) with a fluorine content of more than 60 wt.% and (d) 0-99.5 wt.% LDPE, and (G) optionally 0.1-10 parts weight (pts. wt.) colour component or batch (to 100 pts. wt. (A)-(F)). Also claimed is a process for the production of these moulding materials by extrusion of the polymer melt under low-shear conditions at 200-250 degrees C in a single-screw extruder or similar type of screw machine.
